Out-of-the-box thinking results in scalable, in-the-box solutions.

Our eLoran suite consists of the smallest size, weight, and input power technology currently available. Our partnership with Nautel allows us to deliver unmatched levels of efficiency and redundancy in the smallest, yet most sophisticated, fully solid-state eLoran transmitters available. When coupled with our Timing and Frequency, Command and Control, Differential Reference Station, and ASF Survey equipment, you are choosing a turn-key solution to your complementary PNT needs.

Are you a leader or a spectator in LF Alternative PNT innovation?

UrsaNav’s family of receiver-based products support turnkey eLoran solutions with applications in navigation, precise timing, system control, and differential Loran reference equipment.

Assured peace of mind with “sky-free” technology.

As the market leader in Low Frequency (LF) Positioning, Navigation, and Timing (PNT), we have developed high-powered, low-frequency, ground wave technology that offer the most reliable, scalable, and future-proof solutions available. The utilities that make up our lives – telecommunications, energy, finance, and transportation – depend on it.

UrsaNav’s alternative Positioning, Navigation, and Timing (PNT) solutions ensure that ships equipped with eLoran receivers can navigate safely in some of the busiest shipping regions around the world.

Lifelines assured. Resilience today and tomorrow.

Coast-to-coast, and far out to sea, our best defense against GNSS vulnerabilities is to have an alternative Positioning, Navigation, and Timing capability in place now.

GPS is the gold-standard for the provision of Positioning, Navigation, and Timing (PNT). When GPS/GNSS is available and trustworthy, you should use it. What do you do when it’s not available or not trustworthy? As the global market leader in continent-wide Complementary PNT solutions, we have developed high-power, Low-Frequency (LF), ground wave technology that is the most reliable, scalable, and future-proof available. Besides PNT, we can also provide phase, frequency, and azimuth, and even 3rd-Party Data Channel solutions. Our technology is fully interoperable with, yet completely independent of, GPS/GNSS. We offer “sky-free” PNT directly to users, or as an enabler of other technologies.

Our Technology

We have been involved in every major technology improvement in Loran-C since 1975, and our personnel have been involved in installing, upgrading, modernizing, and/or relocating almost every Loran-C facility in the world.

What’s the future look like after eLoran? We’ve been thinking about the Next Generation of LF for years, and have already developed the concepts and the technology for the next phase of Loran-like, but not necessarily Loran, PNT solutions.

From Concept to Reality: T3 Deployable Solutions

UrsaNav’s advanced eLoran technology allows for new ways to package and deploy eLoran systems. Our innovative “T3” or Temporary, Transportable, or Tactical solutions, include transmitters installed in air transportable containers; antennas that are transportable and deployable within 24 hours; and custom solutions that include everything needed to deploy one or more eLoran transmitting sites to a remote location.

Check out the video below to see our T3 solution in action.

Position, Navigation, and Timing, or PNT, is known as the hidden utility. Despite its widespread use in so many applications and its daily use by billions of people globally, PNT is little known and little understood outside a relatively small group of men and women who specialize in the subject. It is hard to imagine […]

Our CRADA partnership with the Department of Homeland Security, Science and Technology Directorate (S&T), US Coast Guard (USCG), and Harris Corporation continues to yield very good timing data over long distances using eLoran. We’ve also been testing eLoran in specific timing applications such as Wide Area MultiLateration. This information is available on our website, entitled […]

UrsaNav is pleased to be working with Spectracom on the development of this exciting new timing product. It demonstrates the market’s demand and the importance companies have started to place on resilient timing solutions for critical operations and infrastructure. Read More

eLoran Transmitter

The Loran sites at Havre, MT; George, WA, and Fallon, NV will be continuously broadcasting from 0900 (MST) 20 June 2017 through 1200 (MST) on 30 June 2017.

The sites will be operating on the 5990 rate but occasionally may operate at other rates. Only the site at Fallon will be operating as an eLoran site. The sites at Havre and George will be operating as Loran-C sites synchronized to UTC. Read More...
